sota-sandboxing skillA

sota-sandboxing is agent-read markdown (skill) from martinholovsky/sota-skills: State-of-the-art sandboxing and isolation engineering (2026). Use when designing isolation for untrusted code, untrusted input parsing, multi-tenant workloads, or AI/agent execution — and when auditing existing systems for isolation gaps. Covers least privilege, defense in depth, isolation boundary selection (VM/microVM/gVisor/container/process/WASM), Linux primitives (namespaces, cgroups v2, seccomp-bpf, Landlock, AppArmor/SELinux, capabilities), Docker/OCI and Kubernetes hardening, privilege s.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add martinholovsky/sota-skills/sota-sandboxing@git:20260617.c5d2c7b
Exact content
mdr add martinholovsky/sota-skills/sota-sandboxing@sha256:f97c976963fe206c

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
